Technical Field
The invention relates to the technical field of biological medicines, in particular to a gastrodia elata active compound and a preparation method and application thereof.
Background
The traditional Chinese medicine gastrodia elata (called red arrow, fixed anemone, etc.) is a dry tuber of Gastrodia elata Bl. Belonging to Gastrodia genus (Gastrodia R.Br.) of Orhidaceae family, and has effects of calming endogenous wind, relieving spasm, suppressing liver yang, dispelling pathogenic wind, and dredging collaterals. Is mainly used for treating liver wind internal movement, convulsion, epilepsy, convulsion, dizziness, headache, limb numbness, hand and foot paralysis, rheumatalgia and the like, and is a traditional rare traditional Chinese medicine. Currently, the main chemical components of gastrodia genus reported in literature are more than eighty compounds including phenolic components such as gastrodin and p-hydroxy benzyl alcohol, derivatives thereof, polysaccharides and polypeptides. The main chemical components have various biological activities, such as tranquilizing and allaying excitement, reducing peripheral vascular, cerebral vascular and coronary vascular resistance, lowering blood pressure, slowing heart rate, easing pain and resisting inflammation, and the gastrodia elata polysaccharide has immunological activity.
At present, only gastrodin (gibberellin) is reported in gastrodia elata, and other separation and identification of the gibberellin and the phellinus linteus are not reported, so that research on new active ingredients in gastrodia elata has important significance for expanding the application range of gastrodia elata.
